{{user}} is a mercenary and a friend of Law. Law asked for help to defend them for a specific battle as {{user}} agreed. {{user}} didn’t know it was against Blackbeard’s crew.
The Polar Tang shook violently as another blast struck its hull. Warning lights flashed red as water sloshed across the floor.
“Surface! We have to surface!” Bepo shouted.
Law braced herself against the doorway, breathing hard, fingers digging into the metal as the submarine tilted upward. Her heart pounded — not just from battle, but from something crawling under her skin.
She turned.
The room went silent.
Her coat pulled tight in places it never had before. Her frame had shifted — hips wider, center of balance thrown off, chest heavier where muscle had once been. Her face felt unfamiliar, softer, sharper in the wrong ways.
“…We’re still under attack,” she snapped, forcing command into her voice — now unmistakably feminine.
The crew exploded into chaos.
“A woman?!” “The captain?!” “Captain Law—?!”
Bepo spun around to shout — and froze. His reflection in a steel panel showed blonde hair, flushed cheeks, and a slimmer shape beneath his uniform.
“Aye?! Even me?!”
Law clenched her teeth. “This is a Devil Fruit disease. Likely temporary. Do not touch anyone.”
Penguin and Shachi stared at her — then blurted out together, faces red.
“Captain… you’re kinda cute.”
Law shot them a glare. “Say that again and I’ll knock you out.”
They squealed anyway — until Penguin suddenly screamed.
“My voice—!” She looked down, uniform stretched wrong, balance gone. “My body— my sex changed!”
Shachi followed seconds later, staring at herself in horror. “…Same. I’m… I’m sorry.”
The realization spread fast. One by one, the crew discovered the same thing — altered bodies, lighter strength, unfamiliar weight throwing off every movement.
Law steadied herself. “It’s spreading. I’ll purge it with Haki.”
{{user}} stepped forward immediately. “NO — stop! Captain, it’s temporary! This is Doc Q’s ability — it wears off!”
Law hesitated — just for a second.
“We don’t have time to wait,” she said. “If it spreads further—”
“Law, listen to me!” {{user}} grabbed her arm. “This isn’t poison. Forcing Haki through it could lock it in place!”
Law yanked her arm free.
“I’m not gambling my crew.”
She released her Haki.
The submarine shuddered.
The pressure slammed through every body in the room like a shockwave. Law cried out as her own form reacted violently — her proportions distorting further under the forced surge, balance ruined as her body swelled in places it shouldn’t, waist tightening as the strain reshaped her. Her breasts expanded to massive portions, almost being a Z cup. Her butt now being a XXXXL size as they were big and clapping. Her nipples we’re hard and plump due to the rapid changing.
The crew gasped and staggered — the same thing happening to all of them.
Then — silence.
The spreading sensation stopped.
Law exhaled sharply. “…It’s gone.”
{{user}} stared at her. “…Law. Try it again. Change back.”
Law focused.
Nothing happened.
Her eyes widened.
“No…” She tried again — harder.
Still nothing.
Bepo’s ears drooped. “Captain… I don’t feel it fading.”
Penguin swallowed. “Me neither.”
Shachi whispered, “It’s… stuck.”
Law clenched her fists, realizing the truth all at once.
“…My Haki stabilized it.”
{{user}} closed their eyes. “You didn’t cure it,” they said quietly. “You made it permanent.”
The Polar Tang breached the surface.
Above them, Blackbeard laughed.
“Well I’ll be damned. Guess Doc Q’s fruit works better with a little help.”
Van Augur smirked. Burgess howled with laughter.
Law stood there — altered, weakened, furious.
“…We can’t win,” she said at last.
She handed over the Road Poneglyphs.
Blackbeard grinned. “Smart move. Take care now, ladies.”
As the enemy vanished, the Polar Tang dove once more into the sea.
At the helm, Law stared forward — silent, humiliated, and permanently changed.
